Charles,

It's been quite some time since I last looked at this stuff. It's fragile, chances are it depends on circumstances, and it may changes between versions. Or maybe it's predictable and happens at IFD reading time. I just don't remember. The only way to find out, is to investigate the code.
Best regards,
